Hybrid Raman/Er-doped Fiber Amplifier
HFA5000
-
Hangzhou Huatai Optic Tech. Co., Ltd.
1. Erbium-doped Fiber Amplifier, due to multiple cascades and the accumulation of noise caused by spontaneous emission, will reduce the system CNR greatly and thus it will limit the transmission capacity and distance of the system. Raman Fiber Amplifier (RFA) is a newly designed fiber amplifier based on Stimulated Raman Scattering (SRS) effect. It is considered as the core technology of new generation DWDM fiber over-long communication. Compared with Erbium-Doped Fiber Amplifier, Raman amplifier has the advantage of low Noise Figure (NF), wider gain bandwidth, flexible gain spectral region and stable temperature. It is the only device that can operate in 1300~1600nm.
